Equivalent Continuum Model of Multiple Cracking

Original language description

A constitutive model for a material (fiber reinforced cementitious composite) that exhibits multiple cracking is developed. The model represents a cracked solid as a continuum with identical macromechanical properties (equivalent continuum). The constitutive law of the equivalent continuum is obtained as the relationship between overall stress and overall strain of a representative volume element (RVE). The RVE is modeled as a solid element intersected by up to three sets of matrix cracks bridged by fibers. Micromechanics is employed to relate the opening and sliding displacements of these cracks to the tractions transmitted across the cracks by bridging fibers. The constitutive law is implemented into an FEM program, which is used to reproduce an experiment conducted on a shear beam. Good agreement of the analytical and experimental results demonstrates validity of the proposed model
